Description

Die Erfindung bezieht sich auf eine Anordnung zur Erzeugung elektrischer Energie aus einem Magnetfeld. Die Erfindung kann beispielsweise zur Energieeinspeisung von Sensoren verwendet werden.The invention relates to an arrangement for generating electrical energy a magnetic field. The invention can be used, for example, to supply energy to sensors be used.

Aus der DE 39 22 556 C3 ist eine Anordnung zur kontaktlosen Energie- und Sensorsignalübertragung mit einem HF-Sender zum Aufbau eines unmodulierten magnetischen Hochfrequenzfeldes über eine Sendespule bekannt, bei der ein Transponder das hochfrequente Magnetfeld aufnimmt und zu seiner Energieversorgung heranzieht. Mit der aus dem magnetischen Feld gewonnenen Versorgungsenergie werden Sensor und Transponder versorgt.DE 39 22 556 C3 describes an arrangement for contactless energy and sensor signal transmission with an RF transmitter to build an unmodulated magnetic High-frequency field known via a transmitter coil, in which a transponder the high-frequency Absorbs magnetic field and uses it to supply energy. With the Supply energy obtained from the magnetic field becomes sensor and Transponder supplied.

Der Erfindung liegt die Aufgabe zugrunde, eine sehr wirksame Anordnung zur Erzeugung elektrischer Energie aus einem Magnetfeld anzugeben.The invention has for its object a very effective arrangement for generation specify electrical energy from a magnetic field.

Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved in connection with the features of the preamble solved by the features specified in the characterizing part of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß die dreidimensionale Wicklungsanordnung keine spezielle Ausrichtung in Abhängigkeit eines zur Energiespeisung herangezogenen Magnetfeldes erfordert. Die dreidimensionale Wicklungsanordnung ist vielmehr stets in allen möglichen Positionen "automatisch" optimal bezüglich des Magnetfeldes ausgerichtet, was einen optimalen Empfang und eine optimale energetische Ausnutzung ermöglicht. The advantages that can be achieved with the invention are in particular that the three-dimensional Winding arrangement no special orientation depending on one Requires energy supply magnetic field. The three-dimensional winding arrangement rather, it is always "automatically" optimal in all possible positions aligned with the magnetic field, which is an optimal reception and an optimal enables energetic utilization.

US-A-4 788 987 beschreibt einen Positionsdetektor, bei dem eine oder mehrere Anordnungen mit drei senkrecht zueinander angeordneten Wicklungen auf einem kugelförmigen Kern aus magnetisch wirksamen Material elektrische Energie aus drei Erregermagnetfeldern unterschiedlicher Frequenz bilden. Aus den drei entstehenden Wechselspannungen unterschiedlicher Frequenz wird die Position der Anordnung relativ zu den Erregerfeldern berechnet. US-A-4 788 987 describes a position detector in which one or more Arrangements with three windings arranged perpendicular to each other on one spherical core made of magnetically active material electrical energy from three Form excitation magnetic fields of different frequencies. From the three emerging AC voltages of different frequencies will be the position of the arrangement calculated relative to the excitation fields.

Die vorgeschlagene dreidimensionale Wicklungsanordnung ist insbesondere geeignet für eine in der DE 199 26 799 A1 vorgeschlagene Anordnung zur drahtlosen Versorgung einer Vielzahl Sensoren mit elektrischer Energie unter Einsatz mindestens einer von einem mittelfrequenten Oszillator gespeisten Primärwicklung (Primärspule, Sendespule), wobei jeder Sensor mindestens eine zur Energieaufnahme aus einem mittelfrequenten Magnetfeld (Bereich von etwa 15 kHz bis etwa 15 MHz) geeignete Sekundärwicklung (Sekundärspule, Empfangsspule) aufweist. Die dort erforderlichen Sekundärwicklungen können sehr gut durch die vorgeschlagene dreidimensionale Wicklungsanordnung realisiert werden. Der Vorteil der stets "automatisch" optimalen Ausrichtung bezüglich des Magnetfeldes ist insbesondere bei an beweglichen Maschinenkomponenten montierten Sensoren (Näherungssensoren) bedeutsam.The proposed three-dimensional winding arrangement is particularly suitable for an arrangement for wireless supply proposed in DE 199 26 799 A1 a variety of sensors with electrical energy using at least one primary winding fed by a medium-frequency oscillator (primary coil, transmitter coil), wherein each sensor has at least one for energy absorption from a medium frequency Magnetic field (range from about 15 kHz to about 15 MHz) suitable secondary winding (Secondary coil, receiving coil). The secondary windings required there can very well by the proposed three-dimensional winding arrangement will be realized. The advantage of always "automatically" optimal alignment with regard to the magnetic field is particularly in the case of moving machine components mounted sensors (proximity sensors) significant.
